Think Green! ;)
Your target visitor might not be looking directly for your product or service but for related information on the web, so it’s a good idea to give him something special or for free that attracts his interest in our site.
Like a restaurant might give some free recipes, a software company some little free program, free updates or templates and clipart, a bookstore some sample text and reviews of bestsellers, a make up company tips on how to use there products with illustrations or a hotel travel tips or a picture gallery related to there location etc. etc.
Its important to know our clients needs and desires in order to give him some information and help or a free sample that helps to "guide" (lure) him to our website.
Its of uppermost importance to design our website with our target visitor in mind!
